equivalent lift-drag ratio
1Lift (force) — For other uses, see Lift. Boeing 747 8F landing A fluid flowing past the surface of a body exerts a surface force on it. Lift is the component of this force that is perpendicular to the …
2Lift-induced drag — In aerodynamics, lift induced drag, induced drag, vortex drag, or sometimes drag due to lift, is a drag force that occurs whenever a moving object redirects the airflow coming at it. This drag force occurs in airplanes due to wings or a lifting… …
3Drag equation — In fluid dynamics, the drag equation is a practical formula used to calculate the force of drag experienced by an object due to movement through a fully enclosing fluid. The equation is attributed to Lord Rayleigh, who originally used L2 in place …
4Aspect ratio (wing) — In aerodynamics, the aspect ratio of a wing is defined as the square of the wing span divided by the wing area.:AR = {b^2 over S}where: b is the wing span, and: S is the wing area.Informally, a high aspect ratio indicates long, narrow wings,… …
5Powered hang glider — A foot launched powered hang glider (FLPHG), also called powered harness, nanolight or hangmotor, is a powered hang glider harness with a motor and propeller in pusher configuration. An ordinary hang glider is used for its wing and control frame …
6airplane — /air playn /, n. 1. a heavier than air aircraft kept aloft by the upward thrust exerted by the passing air on its fixed wings and driven by propellers, jet propulsion, etc. 2. any similar heavier than air aircraft, as a glider or helicopter. Also …
7Propeller — A propeller is essentially a type of fan which transmits power by converting rotational motion into thrust for propulsion of a vehicle such as an aircraft, ship, or submarine through a mass such as water or air, by rotating two or more twisted… …
